Question

Drink sales for an afternoon at the school carnival were recorded in the table below.
What is the experimental probability that the next drink is a small coffee? Enter your
answer as a simplified fraction.

Answer 1

Given:

The table that represents the drink sales for an afternoon at the school carnival.

To find:

The experimental probability that the next drink is a small coffee.

Solution:

From the given table it is clear that,

The total number of drinks sold = 72+99+63+68+47+58

                                                     = 407

The number of small coffee sold = 63

Now, the experimental probability that the next drink is a small coffee is:

$\text{Probability}=\dfrac{\text{Number of small coffee sold}}{\text{Total number of drinks sold}}$

$\text{Probability}=\dfrac{63}{407}$

It cannot be simplified further.

Therefore, the experimental probability that the next drink is a small coffee is $\dfrac{63}{407}$.
